[0042] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In order to solve the technical problems existing in the prior art, in this embodiment, a three-phase HPLC broadband carrier module is provided, the near end of which is connected to the carrier electric energy meter signal and can collect the data of the carrier electric energy meter in real time. At the same time, the far end is connected to the main station signal, and the broadband carrier module can transmit the collected data of the carrier electric energy meter to the main station. Specifically, Figure 1 As shown, including:

[0044] A broadband carrier chip, a carrier data sending unit, a carrier data receiving unit, a data signal coupling unit, a capacitor power supply unit, a capacitor power supply adjustment unit, a power supply data processing unit and a data acquisition unit. The input end of the broadband carrier chip is signal-connected to the output end of the data acquisition unit, and the data acquisition unit is used to collect relevant operating data of the carrier electric energy meter. The output end of the broadband carrier chip is signal-connected to the input end of the carrier data sending unit, and the input end of the broadband carrier chip is also signal-connected to the output end of the carrier data receiving unit. The output end of the carrier data sending unit and the input end of the carrier data receiving unit are signal-connected to the data signal coupling unit. The output end of the data acquisition unit is signal-connected to the input end of the power supply data processing unit, and the output end of the power supply data processing unit is signal-connected to the input end of the capacitor power supply adjustment unit. The output end of the power supply data processing unit is connected to the capacitor power supply unit, and the capacitor power supply unit is connected to the broadband carrier chip, and the capacitor power supply adjustment unit is also signal-connected to the carrier data sending unit and the carrier data receiving unit.

[0045] From the above, it can be seen that the power supply data processing unit processes the relevant data collected by the data acquisition unit. At the same time, the capacitor power supply adjustment unit controls the capacitor power supply unit based on the relevant data fed back by the power supply data processing unit to provide power for the carrier data sending unit. At the same time, in order to save power, the capacitor power supply unit is appropriately powered off and silenced to save power.

[0046] Among them, the data acquisition unit is used to collect the power outage reporting data of the carrier electric energy meter, the power supply data processing unit is used to receive the power outage reporting data transmitted by the data acquisition unit, and process and calculate the power outage reporting receipts, and the capacitor power supply adjustment unit is used to receive the power outage reporting data calculation results and adjust the power supply voltage of the capacitor power supply unit.

[0047] Specifically, the data acquisition unit is used to collect the power outage reporting data of the carrier electric energy meter, and the specific steps include:

[0048] Obtaining a power failure trigger signal of the carrier electric energy meter, that is, when the carrier electric energy meter is powered off, the data collection command of the collection unit is triggered;

[0049] Based on the power outage trigger signal, obtain power metering data, real-time power consumption data, remaining power data, remaining electricity fee data and fault data;

[0050] The power metering data, real-time power consumption data, remaining power data, remaining electricity fee data and fault data are processed to obtain power outage reporting data.

[0051] At the same time, the power supply data processing unit is used to receive the power outage report data transmitted by the data acquisition unit, and process and calculate the power outage report receipt, including:

[0052] Obtain power outage reporting data and calculate the amount of data to be transmitted for the power outage reporting data; that is, after collecting energy metering data, real-time power consumption data, remaining power data, remaining electricity fee data and fault data, calculate the total data size of the above data, such as the total data size is 200K.

[0053] Compare the amount of data to be transmitted with the data transmission threshold, and determine the data transmission plan based on the comparison result; set a threshold for each data transmission, and determine how to perform data transmission based on whether the comparison result is greater than the data transmission threshold.

[0054] In one case, when the amount of data to be transmitted is less than the data transmission threshold, direct transmission is performed;

[0055] In another case, when the amount of data to be transmitted is greater than the data transmission threshold, the power outage reporting data is split into at least two sub-data amounts to be transmitted, and each sub-data amount to be transmitted is less than the data transmission threshold. For example, the energy metering data and the real-time power consumption data form one sub-data amount to be transmitted, and the remaining power data, the remaining electricity fee data and the fault data form another sub-data amount to be transmitted, so that the two sub-data amounts to be transmitted can be ensured to be lower than the data transmission threshold, thereby facilitating the transmission of the data amount to be transmitted.

[0056] At the same time, the capacitor power supply adjustment unit is used to receive the calculation result of the power outage reporting data and adjust the power supply voltage of the capacitor power supply unit, including:

[0057] Obtain the data transmission distance data and the preset data transmission rate data with the master station, and calculate the data transmission time of the amount of data to be transmitted, including:

[0058]

[0059] Wherein, L is the data transmission distance data, S is the preset data transmission rate data, and T1 is the data transmission time.

[0060] Based on the calculated data transmission time and the amount of data to be transmitted, the power supply voltage of the carrier data transmission unit of the amount of data to be transmitted is calculated, including:

[0061]

[0062] Among them, L is the data transmission distance data, S is the preset data transmission rate data, B is the amount of data to be transmitted, V0 is the power supply voltage, V max is the maximum voltage.

[0063] The voltage applied to the carrier data sending unit is distributed based on the obtained power supply voltage data.

[0064] At the same time, the data transmission distance data and the preset data transmission rate data with the master station are obtained, and the data transmission time of the amount of data to be transmitted is calculated, which also includes:

[0065] Based on the obtained data transmission time, determining the reception time when the carrier data receiving unit receives the return data;

[0066] Based on the data transmission time and the reception time, a silent time of the capacitor power supply unit is determined.

[0067] Furthermore, the silent time is less than the sum of the data transmission time and the reception time, including:

[0068] T3<T1+T2

[0069] Among them, T1 is the data transmission time, T2 is the receiving time, and T3 is the silent time.

[0070] As shown above, T1 is the time for data to be transmitted from the broadband carrier module to the master station, and T2 is the time for the broadband carrier module to receive the data sent by the master station. After the data is sent from the broadband carrier module, it takes an interval of T1+T2 to get feedback. In order to better save the power of the capacitor power supply unit, the electrical connection between the capacitor power supply unit and the broadband carrier chip, the carrier data sending unit, the carrier data receiving unit, etc. is cut off during this time period, and after the silent time T3, the capacitor power supply unit is re-powered. In this way, the power of the capacitor power supply unit can be greatly saved and the power supply time can be extended.

[0071] The present application provides a three-phase HPLC broadband carrier module, comprising a broadband carrier chip, a carrier data sending unit, a carrier data receiving unit, a data signal coupling unit, a capacitor power supply unit, a capacitor power supply adjustment unit, a power supply data processing unit and a data acquisition unit, wherein the input end of the broadband carrier chip is signal-connected to the output end of the data acquisition unit, the output end of the broadband carrier chip is signal-connected to the input end of the carrier data sending unit, the input end of the broadband carrier chip is also signal-connected to the output end of the carrier data receiving unit, the output end of the carrier data sending unit and the input end of the carrier data receiving unit are signal-connected to the data signal coupling unit, the output end of the data acquisition unit is signal-connected to the input end of the power supply data processing unit, the output end of the power supply data processing unit is signal-connected to the input end of the capacitor power supply adjustment unit, the output end of the power supply data processing unit is connected to the capacitor power supply unit, the capacitor power supply unit is connected to the broadband carrier chip, and the capacitor power supply adjustment unit is also signal-connected to the carrier data sending unit and the carrier data receiving unit. By collecting and calculating the amount of data to be transmitted from the power outage report data, and determining the transmission plan according to the amount of data to be transmitted, and based on the data transmission distance, data transmission rate, and the maximum voltage of the capacitor power supply unit, the carrier data transmission unit is matched with an optimized power supply voltage, thereby improving the data transmission effect. At the same time, considering the large amount of data to be transmitted, the amount of data to be transmitted is split into multiple sub-data amounts to be transmitted, which is conducive to the smoothness of data transmission, and by setting the silent time, the loss of the capacitor power supply unit in the power outage state is reduced, so as to prepare for providing a voltage for secondary data transmission after data transmission fails.
